NASTY! Stay away!

Contrary to what some rave reviews, these batteries are worthless and believe me, I have experience in the rechargeable batteries field.
I have loaded (12 in total!) With excellent Chargers Panasonic in optimal conditions.
They heat up quickly and horribly, they take almost no charge, some even make noise (a kind of severe wheezing) on ​​first use and become very hot (4 stacks of 12!). The other processing in an electronic device that normally takes 6 hours with batteries held 11 minutes !!! A shame, a scandal !!!!!! Prefer known brands like Eneloop (times by Panasonic, excellent!) Or even under brands such as' Top Kraft "(also excellent) but certainly not this abomination that made shame in German industry while being very expensive, boasts misleading performance that make you dream (2650 mAh min - max 2850 mAh). In addition, after 30 days impossible to return them to the seller while it's been months that I try to give them a chance in various devices, without success! !! And the European guarantee of 2 years ???? short, shun them!
